10/10. Really, there's nothing else to be said. Impeccable atmosphere, amazing voice acting, incredible graphics, I could go on and on just praising things with "adjective" + "noun".
I especially loved the red herrings, forcing you to actually read the text rather than just skimming through and looking for keywords. I don't know if acids and bases can actually be hidden (as the notes mention) because that never happened in any of my runs.
I don't know how this game could possibly be improved further, but this is easily the one game in the Jam that I'd love to see get expanded.
My one singular, pedantic piece of criticism would be that "Ctrl" just makes you slower, which seems pretty useless. I wish it would make you crouch instead, making it easier to pick up items on the bottom shelves.
